Commission approves Federal tax reduction for Vectren bills Customer bill amounts to decrease by $35 over a 12-month period

Indianapolis, Ind. - The Indiana Utility Regulatory Commission (IURC) approved the final phase of an agreement between Vectren Energy Delivery of Indiana - North (Vectren) and various consumer groups to reflect decreases in natural gas rates as a result of the Federal income tax reduction prescribed in the Tax Cuts and Jobs Act of 2017.

The approval, combined with the first phase approved in June, results in customers who receive Vectren natural gas service seeing their annual energy bill reduced by a combined total of about $35 over a 12-month period.

"Current bills include the cost of income taxes and with this agreement customers will directly benefit from this reduced cost resulting from the lower tax rate," said Mike Roeder, vice president of government affairs and president of Vectren Energy Delivery of Indiana - North. "Vectren is committed to ensuring all reductions approved within the Tax Cuts and Jobs Act of 2017 are received by customers."

Vectren announced its plan to lower rates in February, which was followed by a March regulatory filing with the IURC. The first phase of the plan was approved by the IURC in June and immediately implemented. The additional reductions approved today are expected to be reflected in bills by the end of 2018 or early 2019.
